"Kids won't just love this book. They need it." --Soman Chainani, New York Times bestselling author of The School for Good and Evil

"Each page crackles as we embark on the greatest adventure of all." --Gary D. Schmidt, Newbery Honor winner and author of Okay for Now

Everyone knows there are different kinds of teachers. The boring ones, the mean ones, the ones who try too hard, the ones who stopped trying long ago. The ones you'll never remember, and the ones you want to forget. Ms. Bixby is none of these. She's the sort of teacher who makes you feel like school is somehow worthwhile. Who recognizes something in you that sometimes you don't even see in yourself. Who you never want to disappoint. What Ms. Bixby is, is one-of-a-kind.

Topher, Brand, and Steve know this better than anyone. And so when Ms. Bixby unexpectedly announces that she won't be able to finish the school year, they come up with a risky plan, more of a quest, really, to give Ms. Bixby the last day she deserves. Through the three very different stories they tell, we begin to understand what Ms. Bixby means to each of them--and what the three of them mean to each other.
